Download Solution PDFConcept:
In Pulse code modulation,
Rb = n × fs
where Rb is the bit rate that is in bits per second
n is no of bits per sample
fs is sample per second
Analysis:
number of reference patterns is N;
bits = log2(N);
number of samples = K;
the transmission rate in bits per sample (r) = \(\frac {bits} {samples}\)
r = \(\rm\frac{\log _2(N)}{K}\)
hence correct option is 4.
